NTE74158 fiche technique
NTE74158
Integrated Circuit
TTL Quad 2Lineto1Line Data Selector/Demultiplexer
Description:
The NTE74158 is a quad 1lineto4line data selector/multiplexer in a 16Lead plastic DIP type
package that contains inverters and drivers to supply full onchip data selection to the four output
gates. A separate strobe input is provided. A 4bit word is selected from one of two sources and is
routed to the four outputs. The NTE74158 presents inverted data outputs to minimize propagation
delay time.
Features:
D Buffered Inputs and Outputs
Applications:
D Expand Any Data Input Point
D Multiplex Dual Data Buses
D Generate Four Functions of Two variables (One Variable is Common)
D Source Programmable Counters
